Bestech Australia can now supply a new type of displacement sensors which use magnetic technology. Micro-Epsilon has developed a completely new displacement measurement principle with its new Magnetic Displacement Sensors (MDS). In contrast to the widely used Hall Effect principle, the displacement sensors are based on a method patented by Micro-Epsilon, which is a linear relationship between the position of the magnet and the output signal. As printed coils are used for this measurement principle, the manufacturing method does not depend on semiconductor processes. This makes customer-specific adaptations considerably easier.
Features of displacement sensors from Bestech Australia include:
- The magnetic displacement sensors have an extremely high basic sensitivity, which enables a very simple and low cost evaluation circuit
- With an eddy current sensor as the technological core, very fast, high resolution versions can be achieved with the magnetic displacement sensors
- Compared to Hall Effect sensors, much larger measuring ranges (currently 60mm limit) can be achieved
- In addition, significantly smaller magnets are required with these magnetic displacement sensors, which reduces costs and simplifies installation
- A pulse width modulated signal is available as an output signal, which can be easily read by a microcontroller using a time measurement
